Please, need help with an Imperial Sprinkler System.
Hello,
A few days ago the control box of my Imperial Water system began to chirp. It's a high pitched continuous chirp that had my dogs howling while inside of the house.
I switched the switch from auto to off. The chirping continued. I pushed on the small reset button. Nothing. I went to my breaker box and flipped the switch (next to it in sharpie pen was written "sprinkler system/lights)." It worked, it turned off the annoying, loud and constant chirping. What it also did was turn off the lights to a couple of rooms upstairs and a hallway light.
The next day I flipped the switch back to on to have use of my indoor lights, and the chirping started up again. The chirping lasted for about five min. then turned into a loud, continuous, high pitched humming/buzzing. It will not stop.
What do I do? I live in Arizona. Coincidentally this all occurred just a few days ago during our temperature freeze, whereby, I took all precautions to avoid any waterline, plumbing ruptures etc. To the eye, I have not observed any ruptures or leaks.
Please help.
Thank you.
